BACKGROUND 1. Field of the Invention

Aspects are generally related to the building and querying of an architecture knowledge graph.

2. Description of the Related Art

In large organizations, maintaining an efficient catalog of design information (i.e., design intent) is challenging, and finding and deciphering such information is time consuming. Typically, architecture documentation is stored in a variety of artifacts such as diagrams, wiki sites, presentations, etc. A challenge regarding these methods of documenting system architecture is that the information in the artifact quickly becomes outdated. Additionally, these methods of documenting make it difficult for organizations to understand how a given component, module, or even an entire application, was designed or was intended to operate, since much of the design process is not captured and memorialized in conventional design artifacts. Moreover, as new versions of a technology (e.g., a software) asset are produced, information regarding design changes or updates for the new version may not be captured, and can, therefore, be very difficult to find or understand.

DETAILED DESCRIPTION OF EMBODIMENTS

Aspects are generally related to the building and querying of an architecture knowledge graph.

An architecture knowledge graph can be generated from one or more states of an evaluated architecture. A first state can be called the intended state. The intended state represents a technological system functioning entirely as it was designed to function. A second state can be called the functional state. The functional state represents the technological system as it actually functions, e.g., in an operational or production environment.

Any technological system may be evaluated, and the determined information can be used to generate an architecture knowledge graph. That is, any software program, module, package, etc., may be evaluated for information to include in an architecture knowledge graph. Moreover, firmware, embedded code, etc., may be evaluated. In some cases (particularly when evaluating/determining the functional state of a technological system), an evaluation will take place in conjunction with any hardware that the software is designed to, or actually does, execute on, drive, monitor, enhance, etc. As used herein, an “evaluated architecture” refers to a technological system including any necessary software and hardware of the system that is evaluated for information that will be included in an architecture knowledge graph.

Once identified, an intended state and a functional state of an evaluated architecture can be structured as a knowledge graph. In accordance with aspects, a knowledge graph can be queried by personnel of an evaluating organization to determine what architectures (i.e., systems, such as software systems) exist in the organization's infrastructure and what those systems' capabilities and behaviors are. A knowledge graph is an abstraction that organizes real-world knowledge and data. A knowledge graph can integrate determined information from many different data sources and can be used to visualize and explain the determined information, particularly with respect to other information in the knowledge graph.

A knowledge graph can show and explain relationships between entities. The entities are represented in the knowledge graph as nodes and the relationship between the entities are shown as edges (visualized as connections between the nodes). Labels are used to label the edges and explain the relationship between the nodes. Additionally, knowledge graphs can be used in conjunction with machine learning (ML) in order to infer, or “predict,” previously unknown or undetermined relationships between, and attributes of, the various nodes in the knowledge graph.

A knowledge graph generated from a determined intended state and a determined functional state of an evaluated architecture can include two dimensions: an intended state dimension that represents the determined intended state of an evaluated architecture, and a functional state dimension that represents the determined functional state of the evaluated architecture. Moreover, a knowledge graph may be generated that represents the intended state dimensions and the functional state dimensions of multiple evaluated architectures. For instance, a knowledge graph can be generated that represents the intended state dimensions and the functional state dimensions of each operational software/hardware solution in an evaluating organization's technology infrastructure. In such an example, each operational software/hardware solution would constitute an evaluated architecture, as further defined herein.

In accordance with aspects, a knowledge graph as described herein can take the form of a directed acyclic graph.

The functional state of an evaluated architecture can be determined from the evaluated architecture's observed configuration and functionality. For instance, a functional state of an observed architecture can be based on the evaluated architecture's interactions within its environment (e.g., a production network environment). An exemplary process (i.e., an exemplary node identifying operation) for observing environmental interactions of an evaluated architecture includes using packet capture tools (PCAPS) to understand network flows on a production network of an evaluating organization. The packet captures can be used to determine a functional state of an evaluated architecture based on the contents of the packets and their destination and origin.

Using packet captures, a network topology can be determined based on network traffic. A determined network topology based on data packets transmitted over a network infrastructure can define network nodes based on the packets transmitted between the nodes. The identified network nodes can represent logical nodes. For instance, hardware may be shared between several evaluated architectures. Each evaluated architecture may execute on a virtual operating system (OS). While the virtual operating systems may share allocated hardware, the virtualized OS may be identified as an independent (logical) network node for evaluation purposes.

Network nodes identified through packet captures (or through other node identifying operations/techniques, described in more detail, below) can be cast as architecture graph nodes on a knowledge graph, and each graph node can represent an evaluated architecture. That is, identified network nodes, architecture graph nodes and evaluated architectures can represent a 1-1-1 ratio with each other, where each identified network node represents an architecture node on the knowledge graph, which, in turn, represents an evaluated architecture. An architecture graph node, as used herein, represents a system, program or other logical node (i.e., an architecture) of an evaluating organization on a knowledge graph.

Network/system nodes may also be determined through various other node identifying operations/techniques. For example, internet protocol (IP) addresses and IP address maps and recorded routes may be used to identify network nodes. Other exemplary aspects include examining deployment mechanisms, records, logs, etc., in order to determine network nodes. For instance, deployment pipelines can be examined to determine what architectures have been deployed onto an evaluating organization's technology infrastructure.

Deployment mechanisms may contain data that verifies other sources of network nodes. For instance, a deployment mechanism may specify an IP address that an architecture was deployed to. The IP address, as determined via the pipeline deployment mechanism may verify a network node discovered via a packet capture operation, or vice versa. Once determined and/or verified through any suitable operation, the identified and/or verified network nodes can be cast onto the knowledge graph as corresponding architecture graph nodes.

In accordance with additional aspects, and as noted above, any suitable operation or process for identifying network nodes for inclusion as corresponding architecture graph nodes in a knowledge graph can be employed. Other exemplary node identifying operations for identifying network nodes include inspecting log files from network operating systems; inspecting/analyzing virtual machine (VM) configuration files; capturing and inspecting/analyzing log files from network routers and switches; examining architecture-as-code (AaC) documentation and/or scripts (described in more detail, below), etc.

FIG. 1 is a block diagram depicting network infrastructure nodes captured as corresponding architecture graph nodes in a knowledge graph. Network infrastructure 105 represents the technology/computer network infrastructure of an evaluating organization. Network infrastructure 105 includes node 110, node 112, and node 114. Executing on node 110 is evaluated architecture 120. Executing on node 112 is evaluated architecture 122, and executing on node 114 is evaluated architecture 124. Each of nodes 110, 112 and 114 represent a logical node configured for networked communication on network infrastructure 105. Network infrastructure 105 is configured with appropriate network communication devices such as network switches/routers (not shown), to facilitate networked communication between nodes 110, 112, and 114.

Evaluated architectures 120, 122, and 124 are software components executing on the hardware that has been (either physically or virtually) allocated to nodes 110, 112, and 114, respectively. Evaluated architectures 120, 122, and 124 each may be any software system that an evaluating organization wishes to evaluate and capture in an architecture knowledge graph—e.g., an accounting software system, a funds settlement software system, an asset trading software system, an MRP/ERP software system, a CRM software system, a bank ledger software system, etc., etc.

Architecture knowledge graph 150 is generated using data collected through node identifying operations performed on network infrastructure 105. Architecture knowledge graph 150 is depicted as a directed acyclic graph in the figures and in accordance with aspects.

Node identifying operations include any suitable technique for identifying logical network nodes on network infrastructure 105 (as further described herein). Once a node is identified through suitable node identifying operations, the node is included in architecture knowledge graph 150 as an architecture node.

With continued reference to FIG. 1 , through node identifying operations, node 110 including evaluated architecture 120 was discovered and was included in architecture knowledge graph 150 as corresponding architecture node 160. Likewise, node 112 and evaluated architecture 122 was identified and corresponding architecture node 162 was included in architecture knowledge graph 150. Similarly, node 114 and evaluated architecture 124 were identified and corresponding node 164 was included in architecture knowledge graph 150. Accordingly, architecture knowledge graph 150 is a representation, in graph form, of the logical architectures of network infrastructure 105.

A knowledge graph generated from network nodes can also include attributes about the network nodes as additional nodes in the graph. Further, edges (i.e., connections representing relationships) can be identified between the architecture nodes and the attribute nodes. Each edge connecting an attribute node to an architecture node can have a label that explains the relationship represented by the edge. In this way, a robust graphical representation of a functional state of an evaluated architecture can be represented by a knowledge graph.

Node identifying operations can also be used as attribute identifying operations, in accordance with aspects. That is, results of the techniques discussed herein for identifying network nodes and evaluated architectures can be further examined to identify functional attributes of the identified nodes. For instance, while a packet captured in a packet capture operation may be examined for an origin address and a destination address in order to identify nodes at the origin and the destination, further examination may be carried out to inspect the type of data the packet carries. Based on the origin and destination of the packet, and the type of data therein, attributes about the sending and receiving nodes can be determined.

Attributes determined based on packet inspection can include dependencies. For example, if a receiving node/evaluated architecture consistently receives a certain type of data from a source node/evaluated architecture, it can be inferred that a dependency exists on the source node/evaluated architecture. Packet capture/inspection may also reveal a particular type of data that can imply a certain data classification. These examples with respect to packet capture/inspection are not meant to be limiting, and other attributes may be determinable through the use of packet capture/inspection used as an attribute identifying operation.

Likewise, many other attribute identifying operations may be employed to determine attributes and corresponding attribute nodes for inclusion in the knowledge graph. As discussed above with respect to node identification, deployment mechanisms (e.g., deployment pipelines) can provide many attributes of corresponding nodes and evaluated architectures. For instance, a deployment mechanism may indicate what operating system and/or platform a particular evaluated architecture was deployed on. Deployment mechanisms may also provide a version number of the evaluated architecture; an internal (i.e., internal to the evaluating organization) identification number of the evaluated architecture; a hosting platform of the evaluated architecture (i.e., a data center location, number, etc.); and the like.

An inspection of repositories and source code therein may also provide many attributes of an evaluated architecture. Some attributes that may be determined through repositories and source code include the coding language that an evaluated architecture was written in; dependencies of the evaluated architecture; whether the evaluated architecture is inward facing, outward facing, or both; etc., etc.

In accordance with aspects, some node and attribute identifying operations may rely on documents that include natural language. Natural language documents can be processed with natural language processing (NLP) engines/algorithms in order to determine both architecture nodes and attribute nodes. Examples of documents/artifacts that can be processed with NLP algorithms include configuration files, property files, project object model (POM) files, VM configuration files, etc.

POM files are XML files that contain information about a project and configuration details used by software project management tools (e.g., Maven™) to build a software project. Some exemplary attributes that are recorded in POM files include source code location, build information, required software dependencies, dependency scope, packaging information, etc.

Natural language-formatted documents can offer a reliable source for node/attribute identification, because they are often organized to include a defined set of information. Further, they are often stored in known locations, and therefore can be easily accessed for processing by NLP engines/algorithms. NLP is discussed in further detail, below, with respect to determining an intended state dimension of a knowledge graph. It is contemplated, however, that NLP and the particular NLP techniques discussed herein are equally applicable to generating both a functional state dimension and an intended state dimension of a knowledge graph.

Identified attributes of architecture nodes can be added to the knowledge graph and edges can be drawn between the architecture node and its corresponding attributes. Labels can be added to the edges to define the relationship between the architecture node and the attribute node. Label values can be derived from a corresponding determined attribute. For instance, if an attribute of an evaluated architecture is “data classification,” the relationship may be a “has” relationship, and the value of the attribute may be “highly confidential.” In this example, then, the knowledge graph would represent that the evaluated architecture node has a data classification attribute, and the value of that attribute is “highly confidential”. With regards to a natural language, the relationship label can be representative of the verb, or predicate, of a sentence.

FIG. 2 is a block diagram depicting a knowledge graph generated from a network infrastructure, in accordance with aspects. Attribute identifying operations, as discussed herein, have identified attributes of node 110 and evaluated architecture 120; node 112 and evaluated architecture 122; and node 114 and evaluated architecture 124. These attributes have been included in architecture knowledge graph 150 as attribute nodes 170-179. Graph edges (i.e., connections between the architecture nodes and the attribute nodes) have also been generated and included in architecture knowledge graph 150. Graph edges are represented in FIG. 2 as lines/arrows from an architecture node to an attribute node. The depicted edges represent the relationship between an architecture node and an attribute node, in accordance with aspects.

FIG. 3 is a detailed view of architecture knowledge graph 150, in accordance with aspects. FIG. 3 shows values of attribute nodes 170-179. FIG. 3 further shows the assigned labels of the graph edges.

FIG. 3 depicts the following: attribute node 170 that has a value of “ID_001.” Attribute node 170 is related to evaluated architecture node 160, and the edge has been assigned label 180, which has a value of “has internal ID.” In accordance with aspects, and with respect to a natural language presentation of the data in a knowledge graph, labels can take the form of predicates, while architecture nodes serve a subjects and attributes as objects. Consequently, an exemplary relationship captured in architecture knowledge graph 150 can be read as, “architecture node [160] has [180] internal ID ID_001 [170].”

FIG. 3 further depicts the following attributes determined through attribute identifying operations: attribute node 171 that has a value of “non-confidential;”attribute node 172 that has a value of “Java;” attribute node 173 that has a value of “external;” attribute node 174 that has a value of “low;” attribute node 175 that has a value of “high;” attribute node 176 that has a value of “PII” (personally identifiable information); attribute node 177 that has a value of “public cloud;” attribute node 178 that has a value of “highly confidential;” and attribute 179 that has a value of “3.0.”

FIG. 3 further depicts determined relationships (edges) between the attribute nodes and the architecture nodes and the labels assigned to each edge in the architecture knowledge graph 150. The labels are as follows: label 180 has a value of “has internal ID;” label 181 has a value of “has data classification;” label 182 has a value of “written in;” label 183 has a value of “has dependency;” label 184 has a value of “has risk rating;” label 186 has a value of “incudes;” label 187 has a value of “deployed to;” and label 179 has a value of “has version.”

While some of the figures herein depict graph edges with labels that include an object, it is contemplated that, from a natural, and English, language perspective, objects represent attributes. For instance, in the exemplary relationship depicted in FIG. 3 between architecture node 160, edge 181, and attribute node 178, “data classification” is considered an attribute of architecture node 160 (even though it is depicted as part of the edge label). The attribute “data classification” has a value of “highly confidential.” The relationship is a “has” relationship. In accordance with aspects, then, and as shown in some of the figures herein, an attribute can be shown as part of an edge label, with the attribute's value depicted in the attribute node.

As depicted in FIG. 2 and FIG. 3 , architecture knowledge graph 150 shows a functional state graph dimension that represents a functional, or observed, state of evaluated architectures 120, 122, and 124 as determined through node identifying operations and attribute identifying operations. In accordance with aspects, and as noted above, an intended state dimension that represents a determined intended state of the evaluated architectures can also be generated and included in a knowledge graph.

In accordance with aspects, an intended state of an evaluated architecture can be a theoretical state in that it may be determined based on the architectural design of the evaluated technological system. For example, an intended state may be determined based on architectural diagrams, flow charts, sequence diagrams, stated/anticipated inputs, stated/anticipated outcomes and outputs (which may be based on the anticipated inputs), stated design intentions and goals, etc. That is, the intended state can be determined by evaluating architecture design documents, documentation, and/or artifacts that may have been generated prior to development and/or provisioning of a given evaluated architecture.

Other examples of information that may be determined from such documentation include related pseudo code, anticipated dependencies, anticipated coding languages and platforms, anticipated hardware environments, known application programming interfaces (APIs) that the evaluated architecture will interact with, other known systems that the evaluated architecture will interact with, etc. This information, and other information discovered in architecture design documents can be used to determine an intended state of an evaluated architecture.

Any architectural and/or design documentation or artifacts created and/or maintained by an evaluating organization may be evaluated to determine the intended state of an evaluated architecture. Any design documentation and artifacts used by an evaluating organization to determine an intended state of an evaluated architecture is collectively referred to herein as “architecture design documentation,” or “architecture design documents.”

In some aspects, an evaluating organization may collect and organize a repository of architecture design documentation in order to facilitate ease of access to the design intentions included therein. An architecture design documentation repository may include several different types of architecture design documentation.

In some aspects, an evaluating organization may define a standard architecture design document format, which may be included in a architecture design documentation repository. A standard architecture design document format may be defined to include components of, and/or information from, many different types of architecture design documentation. That is, a standard architecture design document format may include standardized data fields or entries that describe design aspects and intentions of an evaluated architecture. The standardized data fields/entries may be included in the standard architecture design document due to their importance or relevance in understanding the intended state of an evaluated architecture.

Exemplary data/information that may be collected in a standard architecture design document includes any information that may be found in any architecture design documentation. That is, a standard architecture design document may include anticipated data inputs, outputs, and other dependencies, a specified coding language, applied design patterns, a required technology platform, required hardware, memory requirements, processing requirements, anticipated network bandwidth, and so on.

A standard architecture design document may include other information such as an identifier that identifies the project/architecture; an information classification that classifies the type of information produced and or stored; indications of whether the architecture is anticipated to be internal or external facing (or both); a repository location for the code and other components of the architecture; and other organization-specific information.

A standard design document may include details about the data that the architecture is anticipated to process, such as an anticipated data classification (e.g., non-confidential, confidential, or highly confidential), an anticipated data risk profile (e.g., low, medium, high), and/or anticipated restrictions on hosting platforms or locations.

In accordance with aspects, a standard architecture design document may be formatted as a natural-language document. A standard architecture design document formatted as a natural-language document may take advantage of natural language processing algorithms in order to determine the contents therein, and in order to employ various machine learning algorithms on the included contents in order to infer relationships and similarities between evaluated systems described in various standard architecture design documentation.

A standard architecture design document may also take the form of an architecture-as-code (AaC) declaration. The AaC concept includes capturing an intended architectural state of a software system (e.g., an evaluated architecture) in a standardized format. The format may be a natural language format, and the entries can be optimized for processing by an NLP, in accordance with aspects.

An exemplary standard architecture design document format can have entries that define attributes of a system, and the relationship between the defined attributes and the subject system. Exemplary entries can be in sentence form, and may include a subject, a predicate (or verb) and an object. Exemplary entries in a standard architecture design document may include:

-   -   System: System ABC     -   Has internal ID 00123456.     -   Is internal facing.     -   Has data classification confidential.     -   Is an internally developed application.     -   Is written in Java.     -   Uses Spring boot framework.     -   Has latency/response SLO (service level objective) of <3170 ms.     -   Has availability SLO of 98% availability.     -   Has external dependency on XYZ Platform.

The exemplary standard architecture design document entries, above, can be readily processed by an NLP engine that has been trained on the natural language format (referred to herein as “behavior driven architecture language”) of the entries, in accordance with aspects. Behavior driven architecture language includes assertions or intents about an architecture's design written in a natural language (e.g., written in English). A training file may be provided to an NLP algorithm that associates predicates/verbs/verb phrases within the file's entries as relationships. Objects within the entries can be associated with attributes and attribute definitions. The subject system (e.g., System ABC in the example) can be associated with an evaluated architecture.

An NLP engine that has been trained on the behavior driven architecture language can then process standard architecture design documents to determine the intended state of the subject architecture based on the attributes and relationships declared therein. The NLP engine may then output the determined attributes and relationships in a predetermined and machine-readable file format. Exemplary file formats may include JSON, XML, CSV, etc.

In accordance with aspects, a knowledge graph can be generated based on a machine-readable file format. A machine-readable file format can include tags or indicators that organize the output of an NLP engine to maintain the subject-verb-object structure (which corresponds to the nodes and relationships of a directed cyclic knowledge graph). For instance, if an NLP engine produces a JSON formatted file for an evaluated architecture (e.g., System ABC), including any determined attributes, values and relationships, the JSON file can act as a JSON-formatted representation of a knowledge graph (or at least part of a knowledge graph that may include data from many similar JSON files). The contents of the JSON file can be readily formatted, and displayed as, a knowledge graph of the determined intended state of a subject system as declared in a corresponding standard architecture design document. The normalized format of design assertions extracted from architecture design documents and formatted in a machine-readable file format that is represented in a knowledge graph is referred to as behavior graph language.

In the same manner, architectures, attributes, attribute values, and relationship signifiers determined through attribute identifying operations and node identifying operations can be normalized and formatted in a machine-readable file format (i.e., can be formatted in behavior graph language). Subsequently, a functional state dimension of a knowledge graph can be generated from the machine-readable files.

FIG. 6 is a flow chart for generating a knowledge graph from standard architecture design documents, in accordance with aspects. At step 602, standard architecture design documents are generated using a behavior driven architecture language. At step 604, the standard architecture design documents are processed using an NLP engine that has been trained to process the standard architecture design documents and recognize graph relevant relationships asserted with the behavior driven architecture language in which the design document is written. At step 606, a machine-readable file is generated from the output of the NLP engine (e.g., a JSON file). At step 608, a knowledge graph is formatted based on the machine-readable file.

In other aspects, standard architecture design documents may take any suitable or desirable format. Non-ML algorithmic approaches (for example, file “scraping”) may be used to extract data from structured architecture design documents where NLP is not applicable, or in addition to NLP processing. In accordance with aspects, data scraped from architecture design documents may be later processed by an NLP algorithm or other ML algorithm. In accordance with aspects, standard architecture design documents may also take the form of design data collected in a normalized relational database, or an OLAP database, including reports therefrom.

In accordance with aspects, architecture design documentation may be processed as described herein, and an intended state dimension of a knowledge graph may be generated based on the data and information obtained from the processed architecture design documentation. Architecture nodes may be discovered through the processing of the architecture design documentation, and these nodes may be added to a knowledge graph, or a verification process may be undertook to verify that the discovered architecture nodes have already been added to an existing knowledge graph. Thereafter, intended attributes of an evaluated architecture that have been determined through the processing of architecture design documentation can be added to the knowledge graph. Edges connecting the determined intended attributes to their corresponding architecture nodes can also be added to the knowledge graph, and corresponding labels may, in turn, be added to the edges.

FIG. 4 is a block diagram of a system for generating an intended state dimension of a knowledge graph, in accordance with aspects. FIG. 4 depicts architecture documentation repository 410, and intent processing engine 412. Intent processing engine 412 may include NLP engine 414. Architecture documentation repository 410 stores architecture design documents as described herein. Architecture documentation repository 410 may be any suitable data store, such as a relational data base (e.g., a relational database configured to store architecture design documents as binary large objects (BLOBs)), a flat-file architecture, a folder structure, etc.

Intent processing engine 412 is configured to access architecture documentation repository 410 and process the architecture design documents therein. Intent processing engine 412 may include NLP engine 414, which, in turn, may include NLP processing algorithms. Intent processing engine 412 may further include other ML algorithms, or non-ML processing algorithms configured to process the architecture design documents, as described in further detail herein.

With continued reference to FIG. 4 , shown is architecture knowledge graph 150. Architecture knowledge graph 150 is shown as including the determined functional state dimension (as described with respect to FIGS. 1-3 , above), in accordance with aspects. It is contemplated, however, that a determined functional state dimension need not be previously determined or included in architecture knowledge graph 150 in order to determine an intended state and include that state as an intended state dimension in the knowledge graph. Architecture knowledge graph 150 is depicted as having an intended state dimension included. In accordance with aspects, the intended state dimension, including intended attributes of architecture attributes 160, 162, and 164 have been determined by intent processing engine 412 based on architecture design documentation accessed from architecture documentation repository 410.

The intended state dimension that has been included in architecture knowledge graph 150 is shown in broken lines, to help distinguish it from the functional state dimension (that is shown in solid lines) and from the architecture node (shown in solid lines, and shaded). Accordingly, as shown in architecture knowledge graph 150 as depicted in FIG. 4 , the determined intended state dimension includes intended attribute node 190, intended attribute node 191, intended attribute node 194, intended attribute node 195, intended attribute node 197 and intended attribute node 198. The intended state dimension further includes corresponding edges indicating relationships with corresponding architecture nodes.

FIG. 5 is a detailed view of a knowledge graph, in accordance with aspects. FIG. 5 depicts a detailed view of architecture knowledge graph 150, including both an intended state dimension and a functional state dimension. The intended state dimension is shown in broken lines and the functional state dimension is shown in solid lines. The architecture nodes are shown in solid lines and are shaded.

In FIG. 5 , the determined intended attributes of architecture node 160 include intended attribute node 190 that has a value of “ID_001;” intended attribute node 195 that has a value of “medium;” intended attribute node 197 that has a value of “private cloud;” and intended attribute node 198 that has a value of “confidential.” Likewise, intended attributes nodes of architecture node 164 have been determined and include intended attribute node 191 that has a value of “non-confidential;” and intended attribute node 194 that has a value of “low.” Edges corresponding to the determined intended attribute nodes have also been determined and included in architecture knowledge graph 150.

Because of space constraints of FIG. 5 , the edges of the intended state dimension are not shown with labels. However, the edges of the intended state dimension are assigned the same label as their corresponding functional state attributes. That is, the edge connecting intended attribute node 190 has been assigned label 180 (i.e., with a value of “has internal ID”); the edge connecting intended attribute node 191 has been assigned label 181; the edge connecting intended attribute node 194 has been assigned label 184; the edge connecting intended attribute node 195 has been assigned label 184; the edge connecting intended attribute node 197 has been assigned label 187; and the edge connecting intended attribute node 190 has been assigned label 181. Due to space constraints of FIG. 5 , no intended attribute nodes have been shown for architecture node 162, however, it is contemplated that the determining processes as described herein would have determined intended attribute nodes and corresponding edges and would have included them in architecture knowledge graph 150.

In accordance with aspects, an architecture knowledge graph can be generated based on an intended state dimension of a knowledge graph, a functional state dimension of a knowledge graph, or both an intended state dimension of a knowledge graph, and a functional state dimension of a knowledge graph. That is, an architecture knowledge graph can include representations of all architecture nodes, and intended attributes, functional attributes, relationships, etc. (i.e., all properties) of each architecture node determined through all identifying operations performed on an evaluating organization's technology infrastructure (as discussed in detail, above).

The use of standard design documents allows for continuous updating of the documents throughout an evaluated architecture's lifecycle and, in turn, continuous updating of an architecture knowledge graph with evergreen design intent information. Updated design intent information gleaned from continually updated standard design documentation can be used to continually update an intended state dimension of a knowledge graph. Likewise, continuing node and attribute identifying operations on an evaluating organization's technology infrastructure along with updates to the architecture knowledge graph when changes are determined, maintain a fresh functional state dimension of the knowledge graph.

By maintaining fresh intended and functional state dimensions, evaluating organizations can use graph querying functions to efficiently retrieve accurate and up-to-date information about an evaluated architecture. Moreover, fresh intended and functional state dimensions allow querying by time dimensions (e.g., an original intended state versus a later intended state) and querying to determine architecture drift (e.g., the difference, or delta, in the intended state dimension versus the functional state dimension).

In accordance with aspects, an architecture knowledge graph can be queried to access the information stored in the architecture knowledge graph. A query engine may be provided as part of the architecture knowledge graph. In some aspects, the architecture knowledge graph can publish an application programming interface (API) that allows a query engine to pass query parameters to the architecture knowledge graph, and allows the knowledge graph to return data that match the query parameters to the query engine.

The query engine may be configured as a natural language query engine that accepts queries formatted in a natural language format. In aspects, the query engine may use the same NLP logic as described herein with respect to NLP engine 414 of FIG. 4 . That is, the query engine can accept queries formatted as sentences, and be trained to determine the subject, predicate (verb), and object of the sentence query, and to pass these determined sentence parts as parameters to the knowledge graph. The knowledge graph can then retrieve a series of nodes and edges that the form an answer to the query question. The retrieved series of nodes and edges can then be passed back to the query engine for consumption by the user. In some aspects, the query engine can format the returned data in a natural language (e.g., a sentence) format.

FIG. 7 is a block diagram of a system for querying an architecture knowledge graph, in accordance with aspects. FIG. 7 includes architecture knowledge graph 150. Architecture knowledge graph 150 exposes query API 152. Natural language (NL) query engine 705 interfaces with query API 152 and receives queries from NL query engine 705. End users can interface with NL query engine 705 to submit queries and consume the data returned from architecture knowledge graph 150 via NL query engine 705.

FIG. 8 is a logical flow of a natural language (NL) query engine, in accordance with aspects. At step 802, a user interfaces with the NL query engine and passes a natural language query to the NL query engine. An exemplary NL query could be a question in sentence form, such as, “How many applications are running on public cloud platforms?”

At step 804, the NL query engine can process the received NL query with natural language processing to form an appropriate query. For instance, the NL query engine can process the received sentence and generate parameters from the sentence that can be used to search the graph. In accordance with aspects, an NLP engine such as that described herein with respect to building an architecture knowledge graph can be used to process the query, Advantages to using the same, or a similar, NLP engine at the NL query engine as that used to build the graph, is that a same or similar NLP engine will have the benefit of training received to build the graph. For example, the NLP engine may have been extensively trained on behavior driven architecture language, as described herein.

At step 806, the NL query engine can pass the query parameters to the architecture knowledge graph, and the architecture knowledge graph can retrieve a series of graph properties that match the parameters. In accordance with aspects, the NL query engine may be trained to relate or associate the verb phrase “are running” from the example NL query (above) to the “deployment” attribute. That is, the NL query engine may determine that a “deployed to” parameter is an appropriate attribute query parameter with which to search the knowledge graph. Further, the NL query engine may determine, through NLP processing of the exemplary NL query, that a value of the “deployed to” attribute should be “public cloud.” Accordingly, the NL query engine can search the architecture knowledge graph for a series of architecture nodes that have a “deployed to” edge/attribute with a value of “public cloud.” Further, based on the NL query phrase “how many,” the NL query engine can return the count (e.g., in SQL, “COUNT”) of nodes that fit these criteria.

At step 808 the NL query engine can format the retrieved series of nodes and edges into a natural language response and, at step 810, can present the natural language response to an end user. An exemplary response by the NL query engine to the example NL query may be, “There are 30 applications running on public cloud platforms.”

In accordance with aspects, in addition to a search of the knowledge graph to identify nodes and edges that are associated with determined query parameters, machine learning models may be used to enhance the data returned by the query engine. Machine learning (ML) models such as neural networks (e.g., any variant of graph neural networks, such as a graph convolutional network (GCN), a graph attention network (GAT), a graph recurrent network (GRN), etc.) may be used to learn the dependencies of an architecture knowledge graph. That is, appropriate ML models can essentially learn the “shape” of the graph, and of the architecture nodes and their attributes and relations within the graph to enhance the response to queries carried out against an architecture knowledge graph.

In order to enhance query results, ML models applied to the architecture knowledge graph may be used to format a received query into a graph shape or pattern (referred to herein as a “query graph”) and then match the pattern determined from the query to similar shapes within the architecture knowledge graph. This can be especially beneficial when processing complex or novel queries, the responses to which may not be readily identifiable through property searches of the graph.

In accordance with aspects, each response to a user query processed using an ML model may include a confidence score. The confidence score may be based on a number of times similar queries have been submitted and answered, and on user feedback as to the accuracy (or perceived accuracy) of the data received in response to the query. Feedback may be gathered in any suitable manner. In one aspect, the user is asked directly to provide feedback on the perceived accuracy of the query results. In other aspects user feedback can be gathered through social engineering or other indirect ways.

A confidence score for an ML model used in a query engine can be determined based on the number of times a similar question/query has been submitted, processed, and results returned, and further on user feedback based on the returned results. For example, if a novel query is submitted, the ML model provides results, and the submitting user gives favorable feedback to the ML model, the confidence score for that query and similar queries may go up. However, additional positive feedback from other submitting users may be needed to achieve a high level of confidence and, therefore a high confidence score for the submitted query.

High confidence scores can be used as training input to the ML models processing the queries. With each affirmation or positive feedback given, the ML model can be made more accurate because more previously unobserved relationships have been verified through user input.

FIG. 9 is a logical flow for processing natural language queries against an architecture knowledge graph, in accordance with aspects. At step 902, a natural language query can be passed to a NL query engine by an end user via an interface to the NL query engine. At step 904, the NL query engine can process the NL query and generate query parameters with which to query the architecture knowledge graph (e.g., as described above with reference to FIG. 8 ).

At step 906, an ML model (e.g., a graph neural network model) can process the generated parameters to produce a graph of the query parameters. At step 908, the NL query engine can search the architecture knowledge graph for a similar shape or pattern as the graph produced from the query parameters by the ML model. At step 910, graph properties from the architecture knowledge graph that are determined to form a similar pattern as the graph produced from the query parameters can be returned from the graph. At step 912, the NL query engine can use NLP to format the returned graph properties into a natural language response to the natural language query.

However, it should be appreciated that in accordance with some embodiments of the system and method of the invention, it is not necessary that a human user actually interact with a user interface used by the processing machine of the invention. Rather, it is also contemplated that the user interface of the invention might interact, i.e., convey and receive information, with another processing machine, rather than a human user. Accordingly, the other processing machine might be characterized as a user. Further, it is contemplated that a user interface utilized in the system and method of the invention may interact partially with another processing machine or processing machines, while also interacting partially with a human user.
